CYLINDRICAL PHOTOVOLTAIC MODULES
offer new and attractive design aspects for the integration into solar-powered street light fixtures and other off-grid smart city applications. For mast and pole integration, small PV tube diameters in the range of 100 - 200 mm are required. Thin film solar cells on flexible substrates can be easily laminated onto curved surface structures, but the efficiencies are still rather low ( about 11%). To optimize the energy yield of such PV tubes, AGAMINE SARL in Morocco produced a novel fabrication technique for laminating almost inflexible crystalline silicon solar cells with efficiencies up to 23% onto the inner surface of narrow glass tubes. Some advanced high-efficiency solar cells can be bent to a very small radius of curvature without considerable losses in the energy field.
